Open google installer app and press the green button and it will check for all the not installed google apps and it will download all of the gapps required and it shows a screen of installation of apps where you have to press on install and wait for some time and repeat this step for installation of other google apps.

Expected so...cos cyanogen based all 6.0 MM roms has broken hwc ...which was fixed in recent versions of lineage os N roms...if only u can make a miui build on lineage 15.1..it will work

do you mean lineage 14.1 ?, because lineage 15.1 is not developed currently for our galaxy s3
So if anyone can help me building miui 9 for our device which is based on lineage 14.1 could be helpful and i have made an test build of miui 9 based on marshmallow but unfortunately the launcher force closes and because of that the whole ui becomes unresponsive. so if anyone is there to help me out to build miui 9 for our beloved device would be grateful.
